Notes from Designer nitrate : A set made from real blood soaked tissues.I'm sure with a little color work you can get them looking fairly realistic...If you use these be sure to give me credit. It would also be nice to get a note so I can see what you created with them.Maybe while you're waiting for them to download you could leave me a comment. I'd really appreciate it.(all the brushes were used in the preview image. full view to see them in detail.)
